Syntax highlighting not working with new dart files in Android Studio

Hi,

I recently updated to Android Studio 3.6 running on Linux. After the updated, I started up Android Studio to work on my flutter project and I was asked to update the Dart & Flutter plugins for Android Studio so I did just that. After completing the updates I tried to continue working on my project but now I’m having an issue with new dart files when I make them.

The syntax highlighting is not working at all with the new dart files as seen in the first photo.

In the second one, it seems the syntax highlighting is only working with return types, method types and classes

Iv tried disabling the plugins, restart the IDE and then enabling them again with zero luck. I have also disabled my theme plugin in case maybe that is what was causing it but it doesn’t seem to be.

Here is my flutter doctor -v report

@CathalButler Thanks for your suggestions. I realized that after upgrading my Android Studio, Flutter and Dart plugins were disabled waiting to either be upgraded to be kept with their current versions. Making sure they were all enabled once again helped.

I faced the same issue, what I’ve done to overcome it was to copy an existing dart file and rename it. I followed all the suggestion from the guy above tho
